Synchronous machines I — An extension of Blondel's two-reaction theory
Blondel treated salient pole machines by resolving the fundamental space component of m. m. f. along the two axes of symmetry the direct axis of the pole, and the quadrature axis between poles. Using… Expand
A simplified method of analyzing short-circuit problems
- R. Doherty
- Journal of the American Institute of Electrical…
This paper presents the theoretical basis for a theorem by which the practical analysis and visualization of short-circuit phenomena can be greatly simplified. The theorem follows from the… Expand
Toxicity of aerosol propellants in the respiratory and circulatory systems. VI. Influence of cardiac and pulmonary vascular lesions in the rat.
Three propellants were selected for investigation in rats because of their non-uniform effect in mice and monkeys and their alterations in heart rate and electrocardiographic pattern during inhalation of these propellants are largely brought about by release of catecholamines from the adrenal gland.

Teacher Power-Professionalization and Collective Bargaining.
Social responsibility of the engineer
- R. Doherty
- Electrical Engineering
- 1 September 1939
WHETHER engineers should assume a larger measure of social responsibility has been debated extensively during the last decade with practical results that are not impressive, yet there appears to be… Expand
Reactance of Synchronous Machines and its Applications
Part I treats of the calculation and application of the armature self-inductive reactance of synchronous machines. A short, reliable method is given in the form of curves, Figs. 20A, B, C, making the… Expand
Three-phase short circuit synchronous machines-V
This paper is the fifth of a series which the authors have presented on the subject of synchronous machines. Part I was an extension of the fundamental theory; Part II, a treatment of torque-angle… Expand
Synchronous Machines-III Torque-Angle Characteristics Under Transient Conditions
This is the third part of a series of papers on the subject of synchronous machines. The first two were: I. An Extension of Blondel's Two-Reaction Theory, II. Steady State Power-Angle… Expand
Short-circuit current of induction motors and generators
Theoretical considerations and experimental data show that there is in the induction generator, just as in the synchronous machine, a serious initial rush of current which is limited only by the leakage reactance of the machine. Expand
